IEC 60034-9 defines acceptable noise limits, providing a foundation for both occupational safety and health (OSH) and predictive maintenance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why is noise measured?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Noise measurement is valuable in two respects: <strong>employee health<\/strong> In this regard, noise exposure should be kept below legal limits; <strong>care<\/strong> In this respect, noise that is above normal or varies indicates a bearing, fan, or alignment problem. Therefore, noise is complementary to vibration analysis.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What does an increase in engine noise indicate?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Often, early diagnosis of a developing mechanical failure such as bearing wear, imbalance, or misalignment prevents major failures.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Monitor the Acoustic and Mechanical Condition of Your Engines<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Related service: <a href=\"https:\/\/aesinn.com\/en\/test-ve-olcum-hizmetleri\/\">Testing and Measurement Services<\/a>.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\"><div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/aesinn.com\/en\/iletisim\/\">Get a quote \u00bb<\/a><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Short answer: IEC 60034-9 defines the noise (acoustic) limits for electric motors.
